Advocate Health Care is the largest healthcare provider in Illinois. With employees in multiple locations, Advocate wanted to improve its messaging technology to make sure that clinicians and employees could communicate clearly, quickly, and accurately. It decided to unplug its Sun iPlanet email servers and give nearly 29,000 employees subscriptions to Microsoft Exchange Online, a cloud-based email service that is part of Microsoft Online Services. Advocate gained instant access to the latest email software and a foundation on which it can add technologies that contribute to better patient care. Plus, it avoided spending U.S.$4 million on a new email infrastructure. By halving email management work, the IT staff has more time to spend rolling out additional communications technologies. With email running in Microsoft data centers, Advocate has minimized opportunities for business interruption.
